Sorry, the modules efilive can see are ECM, EBCM and SDM. (I knew there are 4 in the car and that I'm not seeing the IPC).
I disconnected/connected SP200 while diagnosing this issue but not before....
I was working on the factory radio in my Camaro this afternoon and found myself in a no-start condition. I think things went south when I turned the ignition on with the radio fuse removed, which...
The E38 may not be able to do class 2 VPW directly but the BCM acts as a gateway between CAN and VPW modules for certain things. And there's a lot of non emissions/non-engine control stuff going on...
But actually the word "dealer" was missing from one sentence in my post which probably confused you. I fixed that.
Sorry I missed this post until now; I mailed the tune a few minutes ago so...
My Z has been in the shop a couple of times with a P0171 DTC (Fuel Trim System Lean bank 1). My (clever) tech figured out this was due to bent pins on the under hood fuse block connector that...
Huh, so it's normal for the secondary O2 output to look lazy. That's sure not what H2OS12 on my Z06 does; most of the time it closely tracks what H2OS11 is doing. I have a log file attached to this...
Ok but the log I captured shows both the primary and secondary O2 sensors going low voltage/rich when the failure mode kicks in. Seems like there is a common cause and I can't really think of a way...
Yep, just got home and had to post the latest!
So far, it appears the O2 sensor replaced last month probably was OK (but why didn't I have any problems until now?) Clearly bank 2, sensor 2 is bad....
It finally threw a code: P0171, Fuel Trim System Lean Bank 1. Sounds like the long term FT has to be 10% or more for 3 minutes.
So one obvious cause would be some kind of air leak except I'm not...
So did the new injector fix it?
Ok, I logged data on the way home from work today and captured a big log which I cropped down to show a couple of failures. The first thing I noticed is that HO2S22 is very lazy. The other is that...
My Z06 crapped out last month with a P0131 (HO2S circuit low voltage bank 1 sensor 1). There had been a couple of short instances of the engine running very rough and one day it stuck. I never got...
The description for {B3321} Skip Shift Min Throttle says:
Throttle position percentage above which CAGS "skip shift" will be allowed. It probably should read "below which" ...
This was E38, OS...
The installation instructions for the June 13th update ask for these build numbers prior to installation:
Scan Tool: 515
ObdiiV7.dll: 644
Tuning Tool: 622I had installed the June 2nd update...
I bet a couple of us would like to see this OS: 12614676 (2007 Z06)
BTW, when I read a bin from my car, I get a bunch of DIC errors (e.g. Service ABS soon) and when I'm done the fuel mileage...
It sounds like there's a shiftlight hiding in there:
So what Z06 specific parameters can be tweaked on the LS7? I'm assuming it's at least possible to change the RPM the exhaust butterflies open. (I pulled the fuse the other day and holy cow! the low...
I know some of you guys are foaming at the mouth but I can't believe how well I've timed this. I bought a Ron Fellows Z06 last week:

I upgraded my 2000 SS from 09381344 to 12212156 over a year ago and haven't had any issues.
Here are my notes: Since then I've done some VE and MAF tuning. (It has passed smog in this...
Ah yes, but then again you get to buy rear brake pads less often.
I don't have ASR on my Camaro but I remember a post back on (the old) ls1.com where a guy complained that he was wearing out his...
The 1998 uses a 3-wire temp sender and its cluster gauge acts analog because it is analog.
The PCM knows the correct temperature. It sends this to the cluster. It's the cluster that's programmed...
It's true that when the EGR is operation, exhaust gas displaces some O2. But all this really means is that you need a little more throttle angle let the missing O2 in so you can burn the same amount...
The EGR has at least one performance benefit; by lowering the combustion temperature, it helps reduce knock. So it's a good thing for part throttle acceleration and high load conditions. Also, the...
I went to the Camaro/Firebird "Invasion" in Bowling Green last September and asked a couple of GM folks about this. The temperature gauge calibration is in the instrument cluster but GM is very is...
